MACHINE FOR SPLICING WIRE.

SPECIFICATION forming part. of Letters Patent No. 383,178, dated May 22,1888.

Application filed November 10. 1887. Serial No. 255,642. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM L. Hans, a citizen of the United States,residing at Lansing, in the county of Ingham and State of Michigan, haveinvented certain new and useful Improvements in Machines for SplicingWires, ofwhich the following is aspecifieation, reference being badtherein to the accompanying drawings.

This invention relates to new and useful improvements in machines forsplicing; wires; and the invention consists in the peculiar constructionand arrangement of the twister mechanism, all as more fully hereinafterdescribed and claimed.

In the drawings which accompany this specification, Figure l is a planof my machine. Fig. 2 is a cross section on line a: a: in Fig. 1. Fig. 3is a detached perspective view of one of the twister-mandrels. Fig. 4 isan end elevation thereof, with its actuating twister gearwheel. Fig. 5is a plan of the mandrels, showing them in relative position at thestarting of the operation, and-with the ends of the wires to be splicedshownin position therein. Fig. 6 is asection at right angles to the planin Fig. 5, and Fig. .7 is a complete splice as made by my machine.

A is a frame or bed-plate, provided with the standards B upon oppositesides thereof, and in which are formed bearings for the twisterwheels 0,which are journaled therein by means of the hollow trunnions 0'. Thesetwisterwheels are bevel-gears and intermesh with the bevel gear-wheel D,placed at right angles thereto and suitably journaled upon the standardE, outside of which a crank-handle, F, is attached for applyinghand-power to the gearwheel D. Each of the twister-wheels 0 is centrallyapertu red, and in these aperturesare slidingly secured the mandrels G,which are forced to rotate with the wheels 0 by means of the feather aupon the mandrels. The outer end of each mandrel is screw-thrcaded, andthey have screw engagement with the brackets H, which are formedintegrally with the frame or are secured thereto in any suit ablemanner.

Each mandrel is centrally apertured and provided with the longitudinalslot 1), communicating with theinterior aperture in the mandrel, and theinner end of the slot b and the central aperture is enlarged, as shownin Fig. 3, for the purpose as hereinafter described.

The standards B extend beyond the periphery of the twister-wheels O, andsuch extension is provided with the guide-slots e, which extend into theeye of the bearing formed therein, and which are adapted to communicatewith corresponding radial slots in the twister-wheels and with the slotb in the man drel.

I is a wire clamp, provided with movable or rigid jaws h h, adapted tobe placed across and in line with the aperture through the mandrels, aswill appear more fully hereinafter.

In practice (J J representing the line-wires to be spliced) the end ofeach line-wire is, preparatory to splicing, provided with the bent endsK K, and the wires are then respectively inserted into the mandrels inthe relative position to each as shown in Fig. 5, where it will be seenthat the enlargements c at the end of the longitudinal slots in themandrels form stops or rests for the bent ends of the wires, permittingthe wires to lie side by side. To introduce the wires in such mannerinto the mandrel, it is necessary to have the guide-slots e in thestandards B register with the radial slots in the twister-wheels O andwith the longitudinal slots 1) in the mandrel, and the parts areadjusted to permit of this being done by turning the handle F into theproper position.

At the same time the two mandrels G approach each other, leaving a spacesu'fficient between them to clamp the wires, so that in the subsequenttwisting of the wires the central portions between the mandrels areprevented from being displaced. This can be accom* plished by anysuitable clamping device, and it will be seen that the clamp shown inthe drawings is adapted to perform this function by simply slipping thejaws on the wires, pro vidcd the slot in these jaws is made to bind thewires. Now, upon motion being given to the handle of the device, it willbe seen that the two mandrels are rotated, and the bent ends K K of thewire are coiled around the line-wires, making the splice, as showninFig. '7. To remove the device from the wire, the slots before describedare made to register, and the clamp removed or detached from the wires,when it can be easily accomplished.

The function of the apertures d in the inner ends of the mandrel is todraw the coil very tight upon the line-wire, and to this end itsdiameter is made just sufticientlylarge to permit the formation of thecoil at aminimum diameter, and the result of this construction is thatby means of this device a coil may be formed more tightly than by anyother means at present employed, and the object of the invention-toadapt the machine for splicing all kinds of electrical wires-is therebyaccomplished in the most perfect manner to insure good metallic contactbetween the parts.

What I claim as my invention is 1. In a machine for splicing wires, thecombination, with a supporting-frame and actuating mechanism,substantially as described, of two oppositely-revolving mandrelsslidingly journaled in bearings in axial line with each other andprovided with a feather, a, engaging the twister-Wheels, a screw-feed,the enlargements c and d atthe inner ends of the mandrels, and the wireclamp I, substantially as described.

2. In a machine for splicing wires, the combination, with the revolvingmandrels G, of the frame A, having the standards B, the twister-wheelsC, jonrnaled on hollow trunnions in thestandards B, and in which themandrels are slidingly secured, the brackets H, having a screwengagementwith the mandrels, the bevel gear-wheel D, and the handle F,all arranged to operate substantially as described.

3. In a machine for splicing wires, the combination oftwooppositely-revolving mandrels journaled in bearings in axial line witheach other and having an endwise-sliding movement in opposite directionin their bearings, central apertures in said mandrels, the longitudinalslots 1), the enlargements c, and the apertures d at the inner ends ofsaid mandrels, substantially as described.

In testimony whereof I affix my signature, in

presence of two witnesses, this 12th day of October, 1887.
